Section 2.
SURFACE VESSELS
6.2.1 SHORE FURNISHED HOSES.  Surface vessels will use only hoses furnished
by the shore station in making ship-to-shore hose connections for conveying
sewage to the pier. Wherever there are pier sewers, a hose supply will be
available, as well as service to bring the hoses alongside.  Sewage hoses
brought to the ship will be clean, in good repair, of the proper type and
lengths, and in sufficient quantity to connect all of the risers on the
vessel to the pier sewer risers in the proper manner.
6.2.2 SHIP CREW TASKS.  The ship's hose handling crew ordinarily will work
only aboard ship and will not handle hose or equipment on the dock.
Sufficient men should be assigned to the crew to haul the hose lengths from
the pier to the weather deck of the ship by hand.  The number will vary:
not less than three men should be assigned, while as many as six men may be
needed for ships on which CHT discharge risers are located 50 feet or more
above the pier.
While approaching the pier, the ship has its CHT system in the holding
configuration, since it is in restricted waters.  The shore crew should be
waiting on the pier with the proper number of clean hoses, ready to assist
in connecting the ship to the sewer.  Two or more men of the ship's hose
handling crew should be standing by at the first CHT discharge riser to be
connected following the ship's mooring.  The following tasks are performed
by the ship's crew (see Figure 6-l):
a.  Immediately after tie-up, the ship's crew heaves hauling line to
the shore crew on the pier.
discharge riser is removed.
b.
The dust cap from the ship's CHT
c. The shore crew bends the line on the female end of the sewage hose
to be raised to the ship's weather deck.
d.  The ship's crew raises the hose to the deck by hauling in the line
by hand, using three men if the deck is close to the pier or four to six men
if the deck is 50 feet or more above the pier; the number of 50-foot lengths
required to make up a single connection will depend upon the size and con-
figuration of the vessel.
e. After the ship's end of the sewage hose is aboard, the ship's crew
waits until the shore end is connected to the pier sewer riser, then removes
the plastic dust plug from the ship's end of the hose.  Then the crew con-
nects the hose to the CHT discharge riser.  The plastic dust plugs will be
collected by the shore crew.
f.  If collapsible rubber sewage hose is being used, the ship's crew
sees to it that there are no sharp bends or kinks in the hose aboard the
vessel and then carefully ties the hose to a rail or stanchion or to a saddle
support four to ten feet from the riser to minimize kinking and to prevent
drips.  Figure 7-3 shows the use of old tire rims as saddles.
